CARL HARRIS, OF LOWE LAKE, CALIFORNIA. GATE.

Specification of Letters Patent.

Patented Nov. 21, 1905.

Application filed August 17, 1904. Serial No. 221,076.

' readily opened and closed.

The invention consists, essentially, in a vertical and horizontallymovable gate counterbalanced by suitable weights, whereby the use ofhinges and fastening devices are avoided.

The invention also consists in the novel features of construction andcombination of parts hereinafter described,particularly pointed out inthe claims, and shown in the accompanying drawings, in which Figure 1 isa perspective view of the gate. Fig. 2 is a side elevation showing thegate partly opened, and Fig. 3 is a vertical section taken at rightangles to Fig. 2.

In constructing the gate employ parallel upright posts A, havingpreferably three pairs of these posts, two pairs being arranged oppositeeach other on the sides of the roadway and the third pair being arrangedofi the roadway and in alinement with the other pairs. The tops of theposts are connected by suitable timbers A and A serving to firmly bracethem. The two outer pairs of posts A carry also adjacent their upperends transverselyarranged end boards A and a rod B has its ends carriedby the end boards A the rod B passing between the posts A forming eachpair and parallel to the brace-timbers A and in a slightly-lower plane.The center pair of posts A are shorter than the opter pairs and at theirupper ends each carries a cross-head A, from the ends of which extenduprights A upon which the timbers A rest. A boxing or framework is thusformed, above which is arranged a transverse timber A, from whichdepends a stop A through which the rod B passes, and the cross-piece Aalso carries a depending bracket, in which is swiveled a pulley C.Grooved rollers D travel on the rod B, which forms an elevated rail ortrack, and carry hangers, to the lower ends of which are connected a barD. At the ends of the bar D are dependent pulleys D The gate E is arectangular frame of any desired construction adapted to move betweenthe posts of each pair and to extend from one pair of posts to anadjacent pair. Pivoted at the center of the upper edge of the gateE is alever F, the lower end of which is pivoted between the posts forming thecenter pair. Cables Gr are connected to the gate adjacent the uppercorners of the gate, and each cable is passed over a pulley D andsupports counterbalancingweights H.

Arranged at one side of the'roadway and some distance from andsubstantially opposite the-center of the frame formed by the posts A andtimbers or beams A is a post J,

having the projecting arm J extending over the roadway. This armcarries'a pulley J A cable K is connected at one end to upper frame ofthe gate E midway the ends of the gate and is passed over the pulleys Cand J the free end of the cable K hanging within easy reach of anoccupant of a vehicle and carrying a weight or handle K on said end.

The operation of the gate will be obvious. By drawing downward on thehandle K the gate will be lifted vertically between the posts of thecentral pair and will swing in the are described by the lever F, thecounterbalancing-weights H aiding in the vertical movement of the gate,and by reason of the weight of the moving mass and the momentum of thebar D and pulleys D, which support the gate when lifted from the ground,the gate will be carried past the position where the lever F is in avertical position and will swing into position between the center pairof posts and the posts A set off from the roadway, leaving the latterclear. The gate can be brought back to its original position in the samemanner, and it will be obvious that to open or close the gate from eachside it is only necessary to duplicate the post J and connecting parts.As no hinges are employed there is no tendency for the gate to sag, andno fastening device is needed. By using the weights H but a slight pullis required on the handle K to move the gate into the desired position.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

l. The combination with posts, a track supported by the posts, avertically and horizontally movable gate between the posts and below thetrack, a lever pivoted adjacent the gate at one end and 'to the gate atthe opposite end, rollers on the track, pulleys suspended therefrom,cables attached at one end I upper corners of the gate-frame and passingover the pulleys carried by the bar, weights on the free ends of thecables, pulleys carried by the posts, and a cable connected to the gatemidway the ends of the gate and passing over the last-mentioned pulleys.
